Hybrid tea rose plant named &#39;jacolman&#39;

ABSTRACT

Hybird tea rose plant having deep red flower color; pointed ovoid bud; deep green, glossy, disease-resistant foliage; and long cutting stems.

SUMMARY OF THE INVENTION

[0001] The present invention relates to a new and distinct variety of rose plant of the rose class which was originated by me by crossing the variety MACauck (U.S. Plant Pat. No. 5,519) with the variety POULman (U.S. Plant Pat. No. 6,264).

BACKGROUND OF THE INVENTION

[0002] The primary objective of this breeding was to produce a new rose variety having a red flowers with the long cutting stems of MACauck combined with the deep red flower color, heavy petal substance and disease resistance of POULman.

BRIEF SUMMARY OF THE INVENTION

[0003] The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

[0004] 1. Deep red flower color;

[0005] 2. Pointed ovoid bud;

[0006] 3. Deep green, glossy, foliage, resistant to mildew and rust; and

[0007] 4. Long cutting stems.

[0008] Asexual reproduction of this new variety by budding on Dr. Huey understock, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

[0009] Flowers of JAColman are larger and of a darker red than those MACauck and JAColman has a taller plant and more high-centered bud form than POULman.

Comparison with Similar Variety

[0010] JAColman differs from Red Queen (Kordes), a similar variety in that JAColman has a larger, more high-centered form and darker flower color.

BRIEF DESCRIPTION OF THE ILLUSTRATION

[0011] The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
